Description

  The present invention relates to a heat shield cover for preventing heat dissipation from a heat source part in an engine part of an automobile, for example.

  Conventionally, for example, in order to prevent heat dissipation from exhaust pipes in engine parts such as automobiles, in particular exhaust manifolds (hereinafter referred to as exhaust manifolds) and catalyst parts, etc. A heat shield cover is used. In addition, the exhaust gas temperature is on the rise to improve fuel economy and clean exhaust gas.

  Although such a heat shield cover can prevent thermal damage to surrounding parts, the temperature of the exhaust pipe rises significantly, and it is necessary to use a material with high heat resistance, which contributes to cost increase. ing.

  Therefore, a heat shield cover that reduces the temperature in the heat shield cover by reducing the temperature inside the heat shield cover by applying black alumite processing to the exhaust pipe surface of the heat shield cover and absorbing the heat radiated from the exhaust pipe with the heat shield cover is proposed. (See Patent Document 1).

  However, in the case of the heat shield cover of Patent Document 1, the temperature in the heat shield cover can be reduced, but the heat radiation radiated from the heat source portion is prevented and the heat damage to the peripheral parts is prevented. There is a problem that the effect of the heat shield cover is reduced.

  In addition, the conventional heat shield covers including the heat shield cover of Patent Document 1 have a base color, that is, a metallic color as it is, or are merely subjected to plating processing based on the heat shield function, and are visually inorganic. Met.

  However, such a heat insulating cover was not satisfactory from the viewpoint of universalization and diversity of tastes. Specifically, for example, since the heat shield cover becomes hot as described above, there is a risk of serious burns when touched. Previously, caution marks were attached to appeal the danger, but by appealing to elderly people with disabilities and persons with disabilities who are handicapped in information acquisition, it is confirmed that all people are dangerous. I think there is a need for a universal design that can be easily recognized. In addition, due to the diversification of tastes, there are users who are particular about not only the appearance of the vehicle such as aero parts and aluminum wheels, but also the design of the engine room and the bottom part, etc. The demand of such sticking users There was no thermal insulation cover with a design that responded to the above.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a heat shield cover that reliably prevents heat dissipation from a heat source in, for example, an engine part of an automobile and can easily cope with various demands.

  The present invention relates to a heat shield cover installed in the vicinity of the heat source in order to shield the dissipation of heat radiated from the heat source, the inner surface being the heat source side surface of the heat shield cover body and the heat source side It is characterized in that at least one surface of the outer surface which is the surface opposite to the surface is colored.

The heat source may be an exhaust pipe (particularly exhaust manifold) or a catalyst part in an engine part of an automobile or the like, or an electronic heating part such as a CPU.
The colored processing applied to the surface can be colored processing of the entire surface or a part of the surface, and the colored includes solid or a combination of multiple colors, overlapping of multiple colors, designs, gradations, etc. Furthermore, it can be a functional color such as an endothermic color, a reflected color, or a warning color. Moreover, the colored processing of the inner surface and the outer surface of the heat shield cover main body can be the same color or different colors.

According to the present invention, for example, it is possible to constitute a heat shield cover that can reliably prevent heat from being emitted from a heat source part in an engine part of an automobile or the like and can easily respond to various demands.
In detail, for example, a material having an appropriate heat resistance performance may be used by applying a color process with endotherm that adjusts the balance between the heat shielding effect and the endothermic effect according to the heat resistance of the exhaust pipe. As a result, the material cost can be reduced.

In addition, for example, by applying colored processing with alert colors such as yellow and red, it is easy for all people to easily appeal to elderly people with disabilities and persons with disabilities who can acquire information. A heat shield cover with some recognizable universal design can be constructed.
Furthermore, the design properties in the engine room, the bottom surface portion, and the like can be improved by performing colored processing having a pattern or pattern with excellent design properties.

  In this way, by performing color processing on at least one of the inner surface and the outer surface of the heat shield cover body, heat dissipation from the heat source portion in the engine portion of an automobile or the like can be reliably prevented and heat dissipation can be achieved. It can easily satisfy various functional and design demands such as warnings and alerts.

As an aspect of the present invention, the colored processing can be configured by painting the surface, surface processing, or a colored sheet fixed to the surface.
The coating can be a heat-resistant paint, a weather-resistant paint, an abrasion-resistant paint, a fluorescent paint having a high alerting function, or the like. The surface treatment can be anodized or coated. The colored sheet can be composed of, for example, a metal sheet such as black aluminum foil, a resin sheet, or the like.
According to the present invention, it is possible to easily perform color processing by a method suitable for the above-mentioned demand.

  Further, as an aspect of the present invention, the heat shield cover body is constituted by a three-dimensional metal cover body in which a metal sheet is formed in a three-dimensional shape corresponding to the three-dimensional shape of the heat source, and the colored processing is performed with an endothermic effect. In addition to the endothermic color processing, the heat insulating cover main body can be applied to at least a portion that requires an endothermic effect.

The endothermic color can be a dark color such as black, amber, dark blue, brown, dark brown, or dark green.
The portion requiring at least the endothermic effect can be a portion requiring the endothermic effect, which is a portion corresponding to a portion requiring heat dissipation of the heat source in the heat shield cover, a peripheral portion including the portion, and further the entire surface.

  According to the present invention, the heat source is covered with the heat insulating cover so as to substantially surround it, and has a reliable heat insulating effect. Furthermore, by applying an endothermic color process to a portion that requires a heat absorption effect corresponding to a portion that requires heat dissipation of the heat source in the heat shield cover, at least a desired heat dissipation action can be achieved in that portion.

  In addition, as an aspect of the present invention, the endothermic color processing is performed on the entire surface of the heat shield cover body, and a part of the heat shield cover body having a heat shield effect is partially reflective. Reflecting means may be provided.

  The reflective means having a high reflectivity is a material whose substrate is highly reflective and has a high brightness, a material whose surface is subjected to a highly reflective surface treatment such as a mirror finish, a color processed with a high brightness color, etc. It can be.

  According to the present invention, it is possible to achieve a reliable heat shielding effect in the portion provided with the reflecting means, and to achieve a desired heat dissipation effect in the portion subjected to the endothermic color processing. Therefore, it is possible to easily achieve both the heat-shielding effect on peripheral components that prevent thermal damage and the heat-dissipating effect of desired wear such as a heat-dissipating effect according to the material of the heat source with a single heat-insulating cover. .

  In addition, for example, a portion having a heat shielding effect in the heat shielding cover body is not provided with a reflection means, and heat absorption color processing is applied to the other portions, so that the heat in one heat shielding cover as described above is obtained. In order to achieve both the heat shielding effect on the peripheral components that prevent harm and the heat dissipation effect according to the material of the heat source, two steps, a step of setting masking and a step of removing masking, increase. Note that the masking at this time needs to be set with high accuracy, resulting in poor workability and low productivity.

  On the other hand, when the reflection means formed in advance is attached to the necessary portion after the endothermic color processing is applied to the whole as in the present invention, only one step of the reflection means mounting process is required. Moreover, since the reflecting means formed in advance is attached, workability is improved and productivity can be improved by ensuring attachment accuracy.

As an aspect of the present invention, the metal sheet can be constituted by a corrugated sheet that has been corrugated.
Even if the corrugated sheet is a thin metal sheet, the corrugating process has high shape workability and shape retention, and therefore, it is light and can easily form a three-dimensional heat shield cover corresponding to the shape of the heat source. In addition, since the heat insulating cover made up of a corrugated sheet with a thin metal sheet has a low heat capacity, in the case of a heat insulating cover processed with an endothermic color, it can radiate the heat absorbed by the heat insulating cover and obtain a desired heat dissipation effect. it can.

The present invention is also a heat shield cover installed in the vicinity of the heat source in order to shield the dissipation of heat radiated from the heat source, and performing black treatment on at least one surface of both surfaces of the metal sheet. Construct a black metal sheet, corrugate the black metal sheet to form a black treated corrugated sheet, and form the black treated corrugated sheet into a three-dimensional shape corresponding to the three-dimensional shape of the heat source to form a black-treated three-dimensional corrugated cover A reflecting means in which a metal sheet having a highly bright surface with high reflectivity is formed in a three-dimensional shape corresponding to the part of the black processed three-dimensional corrugated cover body. , Characterized by being partially fixed.
According to the present invention, it is possible to obtain a heat shield cover that can achieve both a reliable heat shield effect and a desired heat radiation effect.

  In addition, black processing is performed on at least one surface of both surfaces of the metal sheet to form a black metal sheet, and the black metal sheet is corrugated to form a black processing corrugated sheet. Since the black processed three-dimensional corrugated cover body is formed in a three-dimensional shape corresponding to the three-dimensional shape of the heat source, a heat insulating cover whose surface is black-processed easily and reliably can be formed.

  Specifically, when black processing is performed after corrugating, it is difficult to perform black processing to the details in the corrugated shape, but as in the present invention, the black metal sheet having the black processing applied to the surface is corrugated. And since the black process corrugated sheet is comprised, the corrugated sheet by which black processing was reliably carried out to the detail can be formed. Therefore, it is possible to obtain a black-treated heat shield cover having a desired heat dissipation action.

  In addition, since the reflecting means formed in advance is attached to the necessary place in the black-treated three-dimensional corrugated cover body formed of the black-treated corrugated sheet that has been black-treated as a whole, it is only necessary to increase the number of steps of attaching the reflecting means in advance. Since the formed reflecting means is attached, workability is improved and productivity can be improved by ensuring attachment accuracy.

Furthermore, the present invention is a heat shield cover installed in the vicinity of the heat source in order to shield the dissipation of heat radiated from the heat source, and a black sheet is provided on at least one surface of both surfaces of the metal sheet. Laminating and corrugating to form a laminated black corrugated sheet, forming the laminated black corrugated sheet into a three-dimensional shape corresponding to the three-dimensional shape of the heat source to form a laminated three-dimensional corrugated cover, Reflecting means in which a metal sheet having a highly reflective surface with high lightness is formed in a three-dimensional shape corresponding to the part at a part having a heat shielding effect in the cover body is partially fixed.
According to the present invention, it is possible to obtain a heat shield cover that can achieve both a reliable heat shield effect and a desired heat radiation effect.

  In addition, a black sheet was laminated on at least one surface of both surfaces of the metal sheet, and a laminated black corrugated sheet was formed by corrugating, and the laminated black corrugated sheet was made to correspond to the three-dimensional shape of the heat source. Since the laminated three-dimensional corrugated cover body is formed in a three-dimensional shape, a heat shield cover whose surface is black-treated can be formed easily and reliably.

  In detail, since the black sheet laminated | stacked with metal sheets can be fixed by corrugation, the corrugated sheet by which the black process was reliably carried out to the detail can be formed easily. Therefore, a heat shield cover having a desired heat dissipation action can be obtained. Further, since the black sheet is fixed, a uniform black heat shield cover without coating unevenness can be formed.

  In addition, since the reflective means formed in advance is attached to the necessary part of the laminated solid corrugated cover body formed of the laminated black corrugated sheet that has been black-treated as a whole, it is only necessary to increase the number of steps of attaching the reflective means, and the preform is formed in advance. Since the reflected means is attached, workability can be improved and productivity can be improved by ensuring attachment accuracy.

  According to the present invention, for example, it is possible to provide a heat shield cover that reliably prevents heat from being emitted from a heat source in an engine part of an automobile or the like and can easily cope with various demands.

The heat protection main body 6 is configured to have a substantially inverted rice ball shape in a plan view and a substantially dome-shaped three-dimensional shape with the back side and the lower side (lower in FIG. 2) opened.

  The heat shield heat protector 1 is configured by mounting a fixing jig 2 with a buffer function, a caution mark 3, a locking hook 4 and a reflective aluminum plate 10 on a heat protect main body 6.

  The heat protection body 6 is formed in a three-dimensional shape corresponding to the three-dimensional shape of the two exhaust manifolds 101, and is substantially semi-elliptical so as to cover the lower opening portion 1a in such a manner as to straddle two pipe-like exhaust manifolds 101.

  The reflective aluminum plate 10 is a non-painted and flexible thin aluminum plate formed in conformity with the three-dimensional shape of the mounting part, and the front surface 1c and the upper surface portion of the heat protection main body 6 on the outer surface 1A and the inner surface 1B. It is attached to the periphery of the fixing jig 2 with a buffer function below the heat protection main body 6 and the right side (back side left side) of the bent portion with 1b.

  In addition, the reflective aluminum plate 10b mounted around the fixing jig 2 with a buffer function has a circular opening formed in a circular shape around the portion corresponding to the fixing jig 2 with the buffer function. The reflective aluminum plate 10 is fixed to the heat-radiating heat protector 1 by rivets (not shown).

  As shown in FIG. 5, the heat-shielding and heat-dissipating heat protect 1 configured as described above has an exhaust manifold 101 mounted so as to protrude to the front side of the engine 100 in the front-rear direction (left-right direction in FIG. 5). As shown in FIG. 4, it is attached by bolt fixing from the front side using a buffering function fixing jig 2 as shown in FIG.

  Next, the double-sided black corrugated sheet 20 constituting the heat protect body 6 will be described. FIG. 6A shows a perspective view of the double-sided black corrugated sheet 20. 6 (b) shows an II end view in FIG. 6 (a), FIG. 6 (c) shows an II-II end view in FIG. 6 (a), and FIG. 6 (d) shows FIG. The III-III end elevation in (a) is shown.

  As shown in FIGS. 6B and 6C, the double-sided black corrugated sheet 20 includes peaks 21 and valleys 22 alternately and continuously in the X direction, and in the Y direction, As shown in FIG. 6 (d), the height of the trough 22 is a corrugated aluminum plate formed by repeating the top (21a, 22a) and the bottom (21b, 22b) at regular intervals. .

  In addition, the peak part 21 and the trough part 22 form the said corrugated shape by alternately repeating wide and narrow at regular intervals in the X direction. Further, both surfaces of the double-sided black corrugated sheet 20 are painted black. Furthermore, the above-described reflective aluminum plate 10 is formed on both the upper and lower sides of the solid double-sided black corrugated sheet 20 constituting the heat-radiating heat-protecting heat protect 1 as shown by dotted lines in FIGS. 6 (b), 6 (c), and 6 (d). It is fixed in a manner of being sandwiched from.

Then, the manufacturing method of the heat-shielding heat protection 1 of the above structures is demonstrated with FIG.
First, as shown in FIG. 7, a black aluminum plate 30 is formed by black coating 32 on both surfaces of a thin aluminum plate 31 having a predetermined size and flexibility. In this example, the black coating 32 was performed with a matte black heat-resistant paint. However, the present invention is not limited to this, and coating with an endothermic dark paint (for example, glossy black, dark blue, etc.) Instead of the black coating 32, surface processing such as black alumite processing may be performed.

  In this way, the black aluminum plate 30 with the black coating 32 is subjected to corrugation with a corrugating apparatus (not shown) so as to have the corrugated shape as described above, thereby forming the double-sided black corrugated sheet 20.

  Then, as shown in FIG. 8A, the double-sided black corrugated sheet 20 is formed with the above-described three-dimensional heat protection body 6 corresponding to the shape of the exhaust manifold 101, and as shown in FIG. The function-equipped fixing jig 2, the caution mark 3, and the locking hook 4 are attached to predetermined positions of the heat protection body 6.

  Further, the reflective aluminum plate 10 (10a, 10b) is attached to a predetermined portion of the heat protect main body 6 in such a manner that the mounting portion of the heat protect main body 6 is sandwiched from above and below, and the reflective aluminum plate 10 is attached to the heat protect main body 6 with rivets (not shown). To complete heat shielding heat protection 1.

  As shown in FIGS. 4 and 5, the front and rear heat shielding heat protector 1 having the above-described configuration manufactured by such a manufacturing method is sandwiched between the exhaust manifold 101 and the engine 100 from the front-rear direction (left-right direction in FIG. 5). By fixing the bolt from the side using the fixing jig 2 with a buffer function, it is possible to obtain both a desired heat dissipation effect and a heat shielding effect on peripheral components that prevent thermal damage. That is, the diffusion of heat radiated from the exhaust manifold 101 is controlled to achieve a desired heat dissipation effect and heat shielding effect.

  Specifically, a black coating 32 is applied to the entire double-sided black corrugated sheet 20 constituting the heat protection main body 6, and the reflective aluminum plate 10 having high reflectivity is partially applied to a portion having a heat shielding effect in the heat protection main body 6. Thus, a desired heat dissipation effect can be achieved at the portion where the black coating 32 is applied, and a reliable heat shielding effect can be achieved at the portion where the reflective aluminum plate 10 is provided.

  Moreover, since the heat-insulating / heat-dissipating heat protect 1 is composed of a double-sided black corrugated sheet 20 having a heat-absorbing black coating 32 in which the balance between the heat-shielding effect and the heat-absorbing effect is adjusted according to the heat resistance of the exhaust pipe. The exhaust manifold 101 may be made of a material having an appropriate heat resistance, so that the range of material selection is widened and the material cost can be reduced.

  For example, the reflective aluminum plate 10 is not provided, a portion having a heat shielding effect in the heat protection main body 6 is masked, and the black coating 32 is applied to the other portions, so that one heat shielding heat protection 1 as described above. In order to achieve both the heat dissipation effect according to the material of the exhaust manifold 101 and the heat shielding effect on peripheral parts that prevent thermal damage, two steps, a step of setting masking and a step of removing masking, increase. Note that the masking at this time needs to be set with high accuracy, resulting in poor workability and low productivity.

  On the other hand, when the reflective aluminum plate 10 formed in advance is attached to the necessary part after the black coating 32 is applied to the whole as in the heat-shielding heat protection 1, only one step of the mounting process of the reflective aluminum plate 10 is performed. It is enough to increase. Moreover, since the reflective aluminum plate 10 formed in advance is attached, it is only necessary to secure the attachment accuracy, so that workability is good and productivity can be improved.

  Moreover, since the heat-shielding heat protection 1 is configured by the double-sided black corrugated sheet 20 obtained by corrugating the thin aluminum plate 31 having flexibility, the shape processing property and the shape retaining property are high. A three-dimensional heat-dissipating and heat-dissipating heat protect 1 corresponding to the shape can be formed.

  Moreover, since the double-sided black corrugated sheet 20 is composed of the thin aluminum plate 31, the heat capacity of the heat-radiating and heat-dissipating heat protect 1 is reduced, and the heat absorbed by the black and white heat-dissipating and heat-protecting heat protect 1 is radiated. A heat dissipation effect can be obtained.

  Furthermore, the both surfaces of the thin aluminum plate 31 are subjected to black treatment to form a black aluminum plate 30, the black aluminum plate 30 is corrugated to form a double-sided black corrugated sheet 20, and the double-sided black corrugated sheet 20 is connected to the exhaust manifold 101. Since the heat protection main body 6 is formed in a three-dimensional shape corresponding to the three-dimensional shape, the heat-shielding heat-protection heat protector 1 whose surface is blackened can be easily and reliably formed.

  Specifically, when the black coating 32 is performed after corrugating, it is difficult to perform the black coating 32 to the details of the corrugated shape, but as in the present invention, the black aluminum plate having the black coating 32 applied to the surface. Since the double-sided black corrugated sheet 20 is formed by corrugating 30, it is possible to form the double-sided black corrugated sheet 20 that is reliably black-coated 32 in detail.

  In addition, although the above-mentioned heat-shielding heat protection 1 was comprised by the double-sided black corrugated sheet 20 which corrugated the black aluminum plate 30 by which the black coating 32 was carried out, the piece lamination which fixed the black aluminum foil 41 instead of the black coating 32 You may comprise the heat-shielding heat protection 1 with the black corrugated sheet 40. FIG. Specifically, FIGS. 9A, 9 </ b> B, and 9 </ b> C illustrating the II end surface, the II-II end surface, and the III-III end surface of the single laminated black corrugated sheet 40 and the method for manufacturing the single laminated black corrugated sheet 40. As shown in FIG. 10, a thin aluminum plate 31 and a black aluminum foil 41 disposed on one side thereof are laminated and corrugated to form a thin aluminum plate in the corrugated shape shown in FIG. The single laminated black corrugated sheet 40 to which the plate 31 and the black aluminum foil 41 are fixed can be easily configured.

  By using this single laminated black corrugated sheet 40 to constitute the heat-radiating heat-protecting heat protect 1, the black aluminum foil 41 is laminated on the inner surface 1B of both surfaces of the thin aluminum plate 31 and corrugated to produce a piece. Since the laminated black corrugated sheet 40 is formed, and the single laminated black corrugated sheet 40 is formed into a three-dimensional shape corresponding to the three-dimensional shape of the exhaust manifold 101 to form a laminated three-dimensional corrugated cover body, the surface is easily and reliably black-treated. The heat shield heat protector 1 can be configured. Therefore, as shown in FIGS. 4 and 5, by attaching the heat-radiating / heat-dissipating heat protect 1 so as to substantially surround the exhaust manifold 101, it is possible to achieve both a reliable heat-shielding effect and a desired heat-dissipating effect.

  Moreover, since the black aluminum foil 41 laminated | stacked with the thin aluminum plate 31 can be fixed by corrugation, the piece lamination | stacking black corrugated sheet 40 by which black processing was reliably carried out to the detail can be formed easily. Thus, since the separate process for fixing the thin aluminum plate 31 and the black aluminum foil 41 is not required, the cost for comprising the piece lamination | stacking black corrugated sheet 40 can be reduced. Therefore, it is possible to obtain the heat-insulating / heat-protecting heat protect 1 having a desired heat dissipation action. Further, since the black aluminum foil 41 is fixed, the uniform black heat-dissipating and heat-dissipating heat protect 1 having no coating unevenness can be formed.

  Furthermore, as shown in FIG. 11, a black aluminum foil 41 is arranged on both upper and lower sides of the thin aluminum plate 31 and corrugated to constitute a double laminated black corrugated sheet 42, and the outer side surface 1A and the inner side surface 1B. Alternatively, the heat-radiating heat protector 1 covered with the black aluminum foil 41 may be configured.
